Alternate Running Mates For OTL Presidents(Pre-1900)

So, the goal of this thread is to find as many possible running mates for OTL Presidents, as well as specualte about how things might have been different if the other candidates had been chosen.

For example,what if we had Thomas Jefferson as the first VP instead of John Adams?

p.s-I'm just using that as an example, I'm not sure if it's actually posible or not.
